Flunitrazepam, sold under the brand name Rohypnol in some countries, is a sedative benzodiazepine. It can cause drowsiness, impaired coordination, confusion, and memory problems.
Health effects and risks
Combining sedatives with alcohol or other drugs that slow the central nervous system can be dangerous and may suppress breathing. If you suspect you or someone else was drugged or assaulted, seek emergency medical care promptly and contact local sexual-assault support; testing options can be time-sensitive. Memory loss alone cannot establish what happened.
Testing and next steps
Drug screens vary by specimen and by the substances listed on a test’s panel. Check the instructions and panel before selecting a test; do not assume every product detects this substance. A home screen is preliminary. For more on specimen types, read Drug Testing Methods; for a preliminary positive result, read Unexpected or Preliminary Positive Results. The Substance Information hub lists the current staging test options.
